The influence of local recurrence of extremity soft tissue sarcoma on metastasis and survival.
One hundred seventy-five consecutive patients with soft tissue sarcoma of the limb and limb girdle were studied using univariate and multivariate analysis. The most important factor determining risk of local recurrence was the quality of treatment of the primary tumor, with wide or radical surgery plus radical radiotherapy obtaining the best local control. Tumor size, site, and histologic grade were not predictive of local recurrence. The important tumor variables predicting survival were tumor size at first presentation and histologic grade. Tumors with greater than 10 cm greatest diameter and high-grade tumors carried a poor prognosis. Local recurrence was significantly associated with reduced survival, but only when (correctly) considered as a time-dependent variable in multivariate analysis. Irradiation was also significantly associated with poor survival. Review of the literature indicates that local recurrence is believed to have little influence on survival. Since the relevant randomized controlled trials have been small, the evidence is inconclusive.
